Description

ZAPF HINGE

The present invention relates to a pivot hinge for pivotably holding a door on a body, comprising a body-side hinge body and a door-side hinge body which is pivotally held on the body-side hinge body by means of a pivot about a longitudinal axis of the pivot.

Such pin hinges are known from the prior art.

These pin hinges in particular allow completely free access to the interior of the body when the door is pivoted from the closed position by 90 ° to a fully open position.

In the known pivot hinges, the hinge body on the body side is fixed directly to the body by means of suitable fastening means, for example fastening screws. These pivot hinges are adjusted by means of elongated holes provided in the body-side hinge body and / or by plastic deformation of the pivot hinge after the body-side hinge body has been fixed on the body.

The disadvantage here is that the weight of the door must be held by the fitter while the body-side hinge body is being fixed to the body; it may even be necessary for a first person to hold the door in the open position while a second person to hold the body side Fixing the hinge body to the body using the fastening means.

If the pivot hinge is adjusted in such a way that the hinge body on the body side can be fixed in various positions relative to the fastening means on the body by means of elongated holes provided in the same, then these fastening means for setting up the pivot hinge must be released so that the body-side hinge body can be displaced relative to the fastening means , This in turn has the consequence that the weight of the door must also be held by the technician or technicians during the setting up of the pivot hinge.

Finally, setting up the pin hinge by plastic deformation requires a certain amount of experience of the fitter and can impair the function of the pin hinge or even damage it. Furthermore, a pivot hinge set up in this way can only be reused in exceptional cases after removal on another door.

The present invention is therefore based on the object of providing a pivot hinge of the type mentioned at the outset, which is simple to install and easy to adjust.

This object is achieved according to the invention in a pivot hinge with the features of the preamble of claim 1 in that the pivot hinge comprises a base body which can be fixed to the body, the body-side hinge body being detachably attachable to the base body and the base body having a bearing surface for carrying the body-side Has hinge body in the assembled state of the pivot hinge.

The design of the pivot hinge according to the invention makes it possible to first fix the base body of the pivot hinge to the body (by means of suitable fastening means) and then releasably fix the body-side hinge body connected to the door to the base body, the body-side hinge body during assembly before being fixed to the base body on the Support surface of the base body can be set down, which carries the body-side hinge body and thus also the weight of the door, so that the weight of the door does not have to be held by the installer while the body-side hinge body is being fixed to the base body. This makes it easy for individuals to easily mount the door with the pivot hinge on the body.

In addition, the body-side hinge body can be displaced relative to the base body before being fixed on the base body, the bearing surface of the base body also carrying the body-side hinge body and thus the door, so that the weight of the door does not have to be held by the fitter even when setting up the pivot hinge , which considerably simplifies setting up the pivot hinge.

In principle, a support surface of the base body that is inclined with respect to the horizontal would also be suitable for at least reducing the weight force to be held by the fitter during the assembly of the door on the body. - 4th

In a preferred embodiment of the invention, however, it is provided that the support surface of the base body is oriented essentially horizontally in the assembled state of the pivot hinge, so that the base body bears the entire weight of the body-side hinge body and the door over the support surface and no weight force component acts along the support surface , which would have to be compensated by the fitter.

A simple installation of the door on the body is achieved in particular when the body-side hinge body can be pushed onto the base body fixed on the body when the pivot hinge is installed.

Advantageously, the body-side hinge body can be pushed onto the base body fixed to the body in a substantially horizontal direction when the pin hinge is installed; This ensures that the mechanic does not have to do any work during the pushing open process or before the pushing open process in order to lift the door with the hinge body connected to the body.

It is expedient if the body-side hinge body can be pushed onto the base body fixed to the body during assembly of the pivot hinge after the body-side hinge body has been pivotally connected to the door-side hinge body. In this case, the door with the components of the pivot hinge arranged thereon can be completely preassembled and connected to the body in a single work step, without a further assembly step being necessary after the body-side hinge body has been fixed to the base body.

In a preferred embodiment of the pivot hinge according to the invention, the hinge body on the body side has a recess for receiving the base body. This makes it possible for the hinge body on the body side to lie flat against the body in the assembled state, which ensures good power transmission between the body and the door. In addition, the base body is received invisibly from the outside in the recess of the body-side hinge body, which contributes to an advantageous visual impression of the pivot hinge. This also ensures that the fastening means with which the base body is fixed to the body are not accessible from the outside, so that the door cannot be removed by unauthorized persons after the pivot hinge has been removed.

In order to make it easy to set up the pivot hinge after the body-side hinge body has been pushed onto the base body, it is advantageously provided that the body-side hinge body has a first guide element and the base body has a second guide element and that the first guide element and the second guide element interact in such a way that the The body-side hinge body is secured against sliding off the base body after being pushed onto the base body, and the body-side hinge body is displaceable relative to the base body along a direction of displacement.

It is expedient if the direction of displacement is oriented essentially parallel to the plane of the door in the closed state of the door, since this enables the desired position of the pin longitudinal axis in a particularly efficient manner is the pivot axis of the door to adjust relative to the side wall of the body adjacent to the door.

If the direction of displacement is oriented essentially horizontally, this has the advantage that no work has to be carried out by lifting the body-side hinge body with the door during the installation of the pivot hinge by the installer.

No details have yet been given on the type of guide elements.

For example, it can be provided that one of the guide elements is designed as a groove and the other of the guide elements is designed as a tongue.

In particular, it can be provided that the first guide element provided on the body-side hinge body is designed as a groove and the second guide element provided on the base body is designed as a spring.

In order to enable a reproducible setting of the pivot hinge and, in particular if two pivot hinges are present on the door, the body-side hinge body of one of the pivot hinges can be left in a predetermined position relative to the associated base body while the second pivot hinge is being set up, it is advantageous if the pivot-side hinge is set up Hinge body and the base body have positioning means by means of which the body-side hinge body can be positioned relative to the base body in a plurality of predetermined positions spaced apart along the direction of displacement.

The positioning means can in particular comprise grooves and / or elevations running transversely, preferably perpendicularly, to the direction of displacement.

In order to be able to save a separate locking device for the door, it is provided in a preferred embodiment of the pin hinge according to the invention that the pin hinge itself comprises a locking device for holding the door in its closed position. This leads to the saving of additional components and to a reduction in the required assembly time.

Different solutions come into consideration for the type of locking device.

For example, a magnetic locking device could be used, in which a magnetic element is provided on the body side and a magnetizable element on the door side or a magnetizable element on the body side and a magnetic element on the door side.

A more reliable locking function is achieved, however, if the locking device comprises a first locking element provided on the body-side hinge body and a second locking element arranged on the door side, which are locked together when the door is closed so that the door is held back in its closed position.

In particular, it can be provided that one of the latching elements comprises a latching lug and the other latching element comprises a movable pressure element.

The required locking force of the locking device is advantageously obtained in that at least one of the locking elements is subjected to a pretension in the assembled state.

This bias is advantageously generated by means of an elastic element, preferably by means of a spring element.

Easy mounting of the second locking element is achieved in that the door-side hinge body comprises a holding element on which the second locking element can be fixed.

It is particularly favorable if the hinge body on the door side comprises a spacer element, by means of which the distance of the holding element from the longitudinal axis of the pin is fixed. It is thereby achieved that the distance of the holding element and thus the distance of the second locking element from the longitudinal axis of the pin remains unchanged during the adjustment or setup of the pin hinge. The locking force required to unlock the locking elements is thus independent of the position of the body-side hinge body relative to the base body and thus relative to the body, so that a sufficient locking force is ensured regardless of the device of the pin hinge.

In a preferred embodiment of the pivot hinge according to the invention, the second latching element comprises a movable pressure element and a retaining element for the movable one Pressure element and the retaining element can be fixed on the retaining element.

In principle, the pin, by means of which the door-side hinge body is pivotally held on the body-side hinge body, can be arranged on the door-side hinge body and be pivotably mounted in a receptacle in the body-side hinge body.

Alternatively, it is possible that the pin is neither rigidly arranged on the door-side hinge body nor on the body-side hinge body, but is pivotably mounted on the one hand in a receptacle in the door-side hinge body and on the other hand in a receptacle in the body-side hinge body.

However, an embodiment of the pin hinge according to the invention is preferred in which the pin is arranged on the body-side hinge body and the door-side hinge body has a receptacle for the pin.

Further features and advantages of the invention are the subject of the following description and drawing of an exemplary embodiment.

1 to 12, designated in its entirety by 100, includes a cabinet body 102 with side walls 104, a top wall 106, a rear wall 108 (see FIG. 5) and a bottom wall 110 (see FIG. 10).

Furthermore, the sheet metal cabinet 100 comprises a cabinet door 112 which is held on the front side of the cabinet body 102 by means of an upper pivot hinge 114 and a lower pivot hinge 116 about a vertical pivot axis 118.

The cabinet door 112 is provided with a door handle 120 which an operator can grip to pivot the cabinet door 112 about the pivot axis 118 and thus open or close the cabinet door 112.

The upper pivot hinge 114 and the lower pivot hinge 116 are constructed mirror-symmetrically to one another with respect to a horizontal central plane of the cabinet door 112, so that only the structure of the upper pivot hinge 114 is explained in detail below. The individual components of the upper pivot hinge 114 can be seen from the exploded views in FIGS. 13 and 14.

The upper pivot hinge 114 comprises a hinge body 122 on the door side, which is shown in FIG. 15 in a longitudinal section and in FIG. 16 in a plan view from below.

The hinge body 122 on the door side comprises a substantially cuboid-shaped pin receiving body 124, which is penetrated by a pin receiving hole 126 parallel to its longitudinal direction.

At an upper end face, the pin receiving body 124 is connected to a spacer web 128 which extends perpendicularly to the longitudinal axis 129 of the pin receiving hole 126 and carries at its free end a retaining tab 130 which extends parallel to the longitudinal axis 129 of the pin receiving hole 126.

The holding tab 130 is provided with a through hole 132, the central axis 134 of which runs parallel to the longitudinal direction of the spacer web 128.

The through hole 132 of the holding tab 130 has a cylindrical section 136 facing away from the pin receiving hole 126 and a section 138 widening conically towards the pin receiving hole 126.

The boundary wall of the conically widening section 138 forms a truncated cone-shaped contact surface 140.

Another component of the pin hinge 114 is an essentially cuboid pressure element receptacle 154, which is shown in longitudinal section in FIG. 22.

The pressure element receptacle 154 is provided on a first end face 156 with a first threaded blind hole 158 and on a second end face 160 opposite the first end face 156 with a second threaded blind hole 162, both threaded blind holes 158, 162 being aligned coaxially with one another and with the longitudinal axis of the pressure element receptacle 154.

A horizontal insertion channel 152 is formed on the upper edge of the cabinet door 112 and is delimited laterally by a triple-folded edge of an outer door shell 144 and downwards by a single-folded edge of an inner door shell 146 of the double-walled cabinet door 112 (see FIG. 4). When mounting the pivot hinge 114, the pressure element receptacle 154 is inserted into this horizontal insertion channel 152.

Only one of the two threaded blind holes 158 and 162 is required, depending on the installation situation of the pivot hinge; the pressure element receptacle 154 is nevertheless provided with both threaded blind holes 158, 162, so that the same component can be used both in the lower pivot hinge 116 and in the upper pivot hinge 114. As can be seen from FIG. 4, the pressure element receptacle 154 is namely asymmetrical with respect to its longitudinal center plane, since a recess 164 is provided on the underside of the pressure element receptacle 154 for receiving the free end 166 of the outer door shell 144.

As can best be seen from FIG. 7, when the pin hinge 114 is assembled, a compression coil spring 166 is introduced into the first threaded blind hole 158 of the pressure element receptacle 154 facing the end of the horizontal insertion channel 152 and a via the outer end of the compression coil spring 166 in FIG. 24 pressure element 168 shown in longitudinal section.

The pressure element 168 is preferably made of an elastic material, for example of a plastic material.

The pressure element 168 comprises a cylindrical base body 170 which is provided on a rear end face 172 facing the compression coil spring 166 with a blind hole 174 coaxial with the longitudinal axis of the base body 170, on the bottom 176 of which the outer end of the pivot hinge 114 is in the assembled state of the pin hinge Compression coil spring 166 is supported.

A front end face 178 of the base body 170 opposite the rear end face 172 of the base body 170 carries a pressure tip 180 which comprises a cylindrical section 182 adjoining the base body 170 and an adjoining substantially hemispherical section 184 and is aligned coaxially to the longitudinal axis of the base body 170 ,

As can best be seen from FIG. 7, the pressure element 168 arranged in the first threaded blind hole 158 of the pressure element receptacle 154 is in the assembled state of the pin Hinge 114 is biased by the compression coil spring 166 against a retaining sleeve 186, which is shown in longitudinal section in FIG. 23.

As can be seen from FIG. 23, the retaining sleeve 186 comprises a hollow cylindrical section 188, which is provided with an external thread (not shown).

An annular stop 190 protrudes radially inward at a front end of the hollow cylindrical section 188.

At the same end of the hollow cylindrical section 188, an annular collar 192 protrudes radially outward, which is provided with a rear-facing, frustoconical contact surface 194.

Furthermore, the front end of the retaining sleeve 186 is provided with two notches 196 at two diametrically opposite locations, both notches 196 penetrating both the hollow cylindrical section 188 and the stop 190 and the collar 192 and being flush with one another.

A suitable tool can engage in the two notches 196 in order to set the retaining sleeve 186 in rotation about its longitudinal axis 198 and thus screw the retaining sleeve 186 with its external thread into a corresponding internal thread.

When assembling the upper pivot hinge 114, the procedure is such that first the pressure element receptacle 154 is inserted into the horizontal insertion channel 152, then the compression coil spring 166 into the first threaded blind hole 158 Introduced pressure element receptacle 154 and the pressure element 168 is placed over the free outer end of the compression coil spring 166 so that the free outer end of the compression coil spring 166 abuts the bottom 176 of the blind hole 174 in the pressure element 168.

Subsequently, the hinge body 122 on the door side is inserted with the pin receiving body 124 first into a vertical insertion channel 142, which is formed on the hinge-side edge of the cabinet door 112 and is laterally delimited by a triple-folded outer door shell 144 and a single-folded inner door shell 146 of the double-walled cabinet door 112 (see Fig. 17).

The door-side hinge body 122 is pushed into the vertical insertion channel 142 until the underside of the spacer web 128 rests on the upper edge of the vertical insertion channel 142 and the retaining tab 130 of the door-side hinge body 122 comes to lie directly in front of the entrance of the horizontal insertion channel 152.

As can best be seen from FIG. 17, the pin receiving body 124 is provided on one longitudinal side with a recess 148 which receives a free end 150 of the outer door shell 144.

The retaining sleeve 186 is then inserted with the above-mentioned suitable turning tool with the external thread of the hollow cylindrical section 188 into the through hole 132 of the retaining tab 130 and screwed into the internal thread of the first threaded blind hole 158 of the pressure element receptacle 154 until the first end face 156 of the pressure element Record 154 on the retaining tab 130 and the frustoconical contact surface 194 of the retaining sleeve 186 on the frustoconical contact surface 140 of the through hole 132 of the retaining tab 130.

By means of the retaining sleeve 186, the pressure element receptacle 154 and the door-side hinge body 122 are thus connected to one another, so that these two parts can no longer be removed from the horizontal insertion channel 152 or from the vertical insertion channel 142 and are thereby fixed to the cabinet door 112.

The base body 170 of the pressure element 168 is received by the hollow cylindrical section 188 of the retaining sleeve 186 and is biased by the compression coil spring 166 against the retaining sleeve 186 such that the pressure tip 180 of the pressure element 168 protrudes beyond the front end face 200 of the retaining sleeve 186.

A further component of the upper pivot hinge 114 is a hinge body 202 on the body side, which is shown in a rear view in FIG. 18 and in a longitudinal section in FIG. 19.

The hinge body 202 on the body side comprises an essentially cuboid base body 204, from the underside 206 of which an essentially cylindrical pin 208 projects downward.

A rear end face 210 of the base body 204 facing away from the pin 208 is provided with a detent 212, which extends to a front side 214 of the base body 204.

On its rear side 216 opposite the front side 214, the base body 204 is provided with a recess 218 which has an essentially oval cross section.

An upper boundary wall 220 of the recess 218 is provided in its central region with a corrugated surface 222 which has grooves 225 running perpendicular to the longitudinal axis 224 of the base body 204 of the body-side hinge body 202.

On this corrugated surface 222, a threaded through hole 226 opens, which extends from an upper side 228 of the base body 204 through the upper region of the base body 204 into the recess 218.

A groove 230 extends parallel to the longitudinal axis 224 of the base body 204 into the upper boundary wall 220 of the recess 218 from two mutually opposite points of the edge of the mouth of the threaded through hole 226 on the corrugated surface 222.

The lower boundary wall 232 of the recess 218 is formed symmetrically to the upper boundary wall 220; that is, the lower boundary wall 232 is also provided in its central region with a corrugated surface 222 which has grooves 225 oriented perpendicular to the longitudinal axis 224 of the base body 204. On the corrugated surface 222 of the lower boundary wall 232 a conical through hole 233 opens, which extends from the bottom 206 of the base body 204 through the lower region of the base body 204 into the recess 218 and tapers from the bottom 206 towards the recess 218.

When installing the upper pivot hinge 114, the body-side hinge body 202 with the pivot 208 is inserted into the pivot receiving hole 126 of the door-side hinge body 122 after the door-side hinge body 122 has been connected to the pressure element receptacle 154 by the retaining sleeve 186.

A further component of the upper pivot hinge 114 is formed by a base body 234, which is shown in a front view in FIG. 20 and in a top view in FIG. 21.

The base body 234 has an oval cross section and is penetrated by a through hole 238 at each of its semi-cylindrical end regions 236.

The upper side 240 and the lower side 242 of the base body 234 are each provided in their central region with a corrugated surface 244, which have elevations 247 running perpendicular to the longitudinal axis 246 of the base body 234.

An elongated hole 248, the longitudinal direction of which coincides with the direction of the longitudinal axis 246 of the base body 234, extends from the upper side 240 through the base body 234 to its underside 242, the elongated hole 248 both on the top 240 and on the bottom 242 each on one of the corrugated surfaces 244 opens.

A strip or spring 250 extends in each case from opposite ends of the elongated hole 248 in the direction of the longitudinal axis 246 of the base body 204 over the top 240 or the bottom 242 of the base body 234.

Furthermore, it can be seen from FIG. 21 that the base body 234 is provided with a recess 254 on its front side 252 in the area of the through holes 238.

When mounting the upper pivot hinge 114, the base body 234 is with its flat rear side 256 on the end face 258 of a side wall profile 260, which forms an upper boundary of one of the side walls 104 of the cabinet body 102, and on a longitudinal side 262 of a ceiling wall profile 264, which is a front boundary forms the top wall 106 of the cabinet body 192, and is fixed to the side wall profile 260 and to the top wall profile 264 by means of two (not shown) fastening screws which pass through the through holes 238 in the base body 234.

After tightening, the heads of the fastening screws lie against the front 252 of the base body 234 in the region of the recesses 254.

After the base body 234 of the upper pivot hinge 114 and the base body 234 of the lower pivot hinge 116 have been fixed on the cabinet body 102, the pressure element receptacles 154 and the door-side hinge body 122 of both pivot hinges 114, 116 on the as described above Cabinet door 112 have been installed and the body-side hinge bodies 202 of both pin hinges 114, 116 have been inserted into the respective pin receiving bodies 124 by means of the pins 208, the cabinet door 112 with the body-side hinge bodies 202 arranged thereon is thus directed towards the cabinet body 102 in the horizontal direction from the front moves that the body-side hinge body 202 with the upper boundary walls 220 and the lower boundary walls 232 of the recesses 218 on the rear sides 216 of these hinge bodies are pushed onto the upper side 240 and the lower side 242 of the respective base body 234.

During this push-open operation, each of the base bodies 234 is received by the recess 218 on the rear side 216 of the respective body-side hinge body 202.

When the rear sides 216 of the body-side hinge bodies 202 of both pivot hinges 114, 116 are flush with the rear side 256 of the respective base body 234, the springs 250 of the respective base body 234 snap into the grooves 230 of the respective body-side hinge body 202, so that the body-side hinge bodies 202 and so that the cabinet door 112 can no longer accidentally slide off the base bodies 234.

In this position of the body-side hinge bodies 202 relative to the base bodies 234, the body-side hinge bodies 202 are carried by the upper surfaces 240 of the base bodies 234 fixed to the cabinet body 102, which serve as support surfaces. In this state, the cabinet door 112 can therefore be released without being able to detach from the cabinet body 102.

The heads of the fastening screws, with which the base bodies 234 are fixed to the cabinet body 102, for example cylinder head screws with hexagon socket, are accommodated in this position in the recesses 254 on the front sides 252 of the base body 234, so that the part lying between the recesses 254 on each front side 252 of a base body 234 comes to bear flat against the rear wall 266 of the respective recess 218 of the body-side hinge body 202.

Furthermore, in this position, the corrugated surfaces 222 of the body-side hinge bodies 202 and the corrugated surfaces 244 of the base bodies 234 engage in one another, so that a displacement of the body-side hinge bodies 202 relative to the base bodies 234 along one of the longitudinal axes 224 of the body-side hinge bodies 202 and the longitudinal axes 246 of the base bodies 234 parallel displacement direction 268 (see, for example, FIG. 7) is possible, however, resistance must be overcome for such a displacement.

To adjust the upper pivot hinge 114 and the lower pivot hinge 116, the body-side hinge bodies 202 are displaced relative to the base bodies 234 along the direction of displacement 268 until the pivot axis 118 of the cabinet door 112 defined by the longitudinal axes of the pivot 208 has received the desired position.

In particular, the pivot hinges 116 and 118 are to be adjusted such that the inner wall of the cabinet door 112 in the fully open state, that is to say after the cabinet door 112 has been pivoted through 90 ° about the pivot axis 118 from the Closed position, essentially flush with the inner wall of the side wall 104 of the cabinet body 102 adjoining the cabinet door 112, so that the interior of the sheet metal cabinet 100 is fully accessible when the cabinet door 112 is open.

The corrugations of the body-side hinge bodies 202, on the one hand, and the base body 234, on the other hand, interact with the corrugations, and the body-side hinge bodies 202 can be positioned relative to the base bodies 234 in a plurality of positions equidistantly spaced apart from one another along the displacement direction 268.

If the body-side hinge bodies 202 have been positioned in a suitable manner relative to the base bodies 234, the cabinet door 112 is brought into the open position shown in FIGS. 8 to 12 and each of the body-side hinge bodies 202 can be detached from the associated base body 234 by means of a countersunk screw 270 Specified which is passed through the through hole 233 in the respective body-side hinge body 202 and through the elongated hole 248 in the respective base body 234 and screwed into the threaded through-hole 226 of the respective body-side hinge body 202.

After tightening, each of the countersunk screws 270 rests with its head against the boundary wall of the conical through hole 233 of the respective body-side hinge body 202.

After the countersunk screws 270 have been tightened, the corrugated surfaces 222 of the body-side hinge bodies 202 and the corrugated surfaces 244 of the base bodies 234 can no longer be separated from one another be released in order to bring about a displacement of the body-side hinge bodies 202 relative to the base bodies 234 along the displacement direction 268. The assembly of the cabinet door 112 on the cabinet body 102 by means of the pivot hinges 114 and 116 is thus completed.

The pin hinges 114 and 116 not only enable the cabinet door 112 to be opened by pivoting the cabinet door 112 about the pins 208; rather, the pivot hinges 114 and 116 also function as a locking device which retains the cabinet door 112 in its closed position.

As can be seen in particular from FIG. 7, the pressure element 168 of each pivot hinge in the closed position of the cabinet door 112 presses with its pressure tip 180 against the rear end face 210 of the base body 204 of the respectively assigned body-side hinge body 202. The pressure tip 180 engages behind the respective one Latch 212, which extends to the front 214 of the base body 204.

Since the hinge body 202 on the body side is fixed to the base body 234 and the base body 234 is in turn fixed to the cabinet body 102, the cabinet door 112 can be opened and thus the pressure element 168 can be moved away from the rear end face 210 over the latching lug 212 only when the pressure element 168 is moved away from the rear end face 210 against the restoring force of the compression coil spring 166.

Claims

To open the cabinet door 112, a locking force must therefore be overcome, which is essentially proportional to the protrusion of the locking lug 212 over the rear end face 210 of the base body 204 of the hinge body 202 on the body side. The pressure element 168 has been moved over the locking lug 212 by applying this locking force , it is moved again by the restoring force of the compression coil spring 166 against the retaining sleeve 186 until the front end face 178 of the pressure element 168 abuts the annular stop 190 of the retaining sleeve 186. The stop 190 prevents the pressure element 168 from falling out of the threaded blind hole 158 of the pressure element receptacle 154 when the cabinet door 112 is open. PATENT CLAIMS
